[bug]: On onRest Callback, not really arrives stand-still

Which react-spring target are you using?

• @react-spring/web
• @react-spring/three
• @react-spring/native
• @react-spring/konva
• @react-spring/zdog

What version of react-spring are you using?

9.5.5

What's Wrong?

when on onRest callback, I expect "top" value to 100, but it is not.

const props = useSpring({
    from: { top: 0 },
    to: { top: 100 },
    onRest: () => {
      console.log(ref.current?.style.top); // Wrong: it is not 100, about like 99.7959px
      window.requestAnimationFrame(() => {
        console.log(ref.current?.style.top); // Right: it is 100
      });
    }
});

Start with src/App.js in the linked CodeSandbox and reproduce the @react-spring/web example using useSpring and onRest. Compare ref.current.style.top inside onRest with its value in the next requestAnimationFrame, then trace the relevant callback and style-update path. Done means the callback behavior matches the expected value and the regression is covered by a test.
